Southeast Alaska Forecast Discussion National Weather Service Juneau AK 511 AM AKDT Thu Sep 23 2021

SHORT TERM. A deepening low over the W gulf will move N towards Prince William Sound today. Storm force winds expected near Cape Suckling this morning with gales over the E gulf expanding into the S inner channels early in the morning and SCA winds developing over the rest of the channels through the morning. Winds also become gusty over land areas with gusts to 40-50mph expected for portions of the panhandle today. This storm will also bring periods of mdt- hvy rain as well. Sat derived rain-rate products show two areas of .10-.25 in/hr approaching the coast. The first is just off the NE gulf coast and the other is approaching Dixon Entrance attm. Precip will transition to showers early this afternoon for the NE gulf coast and through the evening for the rest of the panhandle. Widespread rainfall totals of 1-1.5 inches expected with NE gulf coast and S panhandle in store for 3-4 inch totals through early Fri. Area rivers and streams will rise, but no flooding is expected at this time. Maintained the mention of TS for the NE gulf and coastal areas tonight as instability parameters continue to show favorable conditions. Showers and winds will gradually diminish Fri as the low slowly fills and dissipates. Forecast confidence remains above average as solutions remain in good agreement on wet and windy autumn weather into Friday for SE AK.

LONG TERM. /Saturday through Wednesday night/ . The extended period continues to be an active period for SE Alaska and the surrounding waters as low pressure systems move through the Gulf and into the panhandle. However, breaks will occur for some areas and it is looking increasingly likely that there could be drier weather, especially through Saturday and Sunday. Rain could return for some locations by the end of Sunday, guidance continues to show that a system may impact parts of the area. However, ensembles have continued to indicate a preference towards a more southerly track for this low. Should this verify, much of the northern panhandle could be spared from much of the associated weather as offshore flow helps filter in drier air from the interior, cutting off a significant portion of the moisture transport. The same cannot be said for southern areas however, and should the current prognostic reasoning continue to hold, it will be a wet start to the work week for many. After this system, ensembles are hinting at yet another system arriving on Wednesday, but growing run to run divergence means that giving details with any degree of confidence is difficult. Alongside the active weather, cooler air will continue to filter into the area at various times, with 850 mb temperatures progged to be below -2C on more than one occasion across much of the area.

AVIATION. Ceilings across Southeast Alaska are expected to deteriorate from visual conditions to marginal as the front approaches, then deteriorating further to instrument conditions for both CIGS and VSBY with frontal passage. Still, the biggest impact to aviation activities will be turbulence and low level wind shear. Low level winds between 2000 and 3000 ft are at 60 to 70 kts over the outer coast in advance of the front and running parallel to the coastline from south to north. Further south, near the triple point, southwesterly winds flowing over southern Prince of Wales Island are even stronger at 90 to 100 kts but at a higher altitude. Model winds are in good agreement with wind speeds measured off of the weather radar located at Biorka Island. Topography over Southeast Alaska will disrupt these winds as the front moves inland, but southerly wind speeds at typical GA altitudes will still be in excess of 50 kts through at least mid morning. The situation improves somewhat by late afternoon, but low level winds will veer to the southwest overnight and continue to produce widespread turbulence through Friday mid-morning.

AJK WATCHES/WARNINGS/ADVISORIES. PUBLIC . Strong Wind until 1 PM AKDT this afternoon for AKZ026. Strong Wind until 10 AM AKDT this morning for AKZ023-027. Strong Wind through this afternoon for AKZ025. Strong Wind from 10 AM AKDT this morning through this afternoon for AKZ017-028. MARINE . Storm Warning for PKZ052. Gale Warning for PKZ033-035-036-041>043-051-310. Small Craft Advisory for PKZ011>013-021-022-031-032-034-053.
